Administration of the MapR Database is done primarily via the command line (maprcli) or with the MapR Control System (MCS). Regardless of whether the MapR Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter
options. MapR Database administration is associated with tables, columns and column families, and table regions.

MapR Database supports two types of table: binary tables and JSON tables. This section covers how to create, edit, and delete tables,
as well as how to set parameter values, display parameter values, grant permissions and access, replicate tables, and
more using the MapR Control System and the CLI.

This section covers overviews of column families in binary tables and JSON tables, how to create column families,
alter them, delete them, set permissions on them, and set and display parameter values.

To set up the Change Data Capture (CDC) feature, the following must exist or be created: a MapR Database source table (JSON or binary), a MapR Event Store For Apache Kafka changelog stream, a MapR Event Store For Apache Kafka stream topic, and a MapR Database table changelog relationship between the source table and the destination stream topic.

The MapR Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight
client applications and the MapR cluster. This section describes considerations when upgrading the service, how to modify
configuration settings, and how to administer and manage the service.
